Example
C#
using Leadtools; 
using Leadtools.Dicom; 
 
 
public void DicomLayerSample() 
{ 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomDataSet dicomDataset = new DicomDataSet()) 
   { 
      // We can also initialize in here the "Grayscale Softcopy Presentation State" class 
      dicomDataset.Initialize(DicomClassType.Undefined, DicomDataSetInitializeType.ExplicitVRLittleEndian); 
 
      //We can remove individual layers by calling RemoveLayerByIndex and RemoveLayerByName 
      dicomDataset.RemoveAllLayers(true); 
 
      DicomGraphicLayer graphicLayer = new DicomGraphicLayer(); 
 
      graphicLayer.LayerOrder = 1; 
      graphicLayer.LayerDescription = "First Layer"; 
      graphicLayer.LayerName = "LAYER0"; 
      graphicLayer.Grayscale = 0; 
      graphicLayer.RgbLayerColor[0] = 255; 
 
      dicomDataset.CreateLayer(graphicLayer); 
 
      Debug.Assert(dicomDataset.GetLayerIndex("LAYER0") == 0); 
 
      DicomGraphicLayer graphicLayer1 = dicomDataset.GetLayerInformation(0); 
      Debug.Assert(graphicLayer1 != null);

      graphicLayer.LayerName = "LAYER1"; 
      dicomDataset.SetLayerInformation(0, graphicLayer); 
 
      Debug.Assert(dicomDataset.LayerCount == 1);

      DicomElement layer = dicomDataset.GetLayerElementByIndex(0); 
      Debug.Assert(layer != null); 
 
      dicomDataset.RemoveLayerGraphicObjects(layer); 
      Debug.Assert(dicomDataset.GetLayerGraphicObjectCount(layer) == 0); 
 
      dicomDataset.RemoveLayerTextObjects(layer); 
      Debug.Assert(dicomDataset.GetLayerTextObjectCount(layer) == 0); 
 
      dicomDataset.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "PresentationState.dcm"), DicomDataSetSaveFlags.None);
